Detailed Description
The invention is further described below with reference to the accompanying drawings, as shown in fig. 1:
the invention relates to an elastic passing method for a highway in severe weather, which comprises the following steps:
s1, dividing a target road section into an unaffected region, an affected transition region and an affected region;
s2, setting traffic identification information for the vehicle; the traffic identification information comprises an entry point and an exit point; the driving-in points and the driving-out points are all positioned in the range of the unaffected area or the affected transition area;
s3, monitoring weather change conditions of a target road section, and adjusting an unaffected area, an affected transition area and an area range of the affected area according to the weather change conditions;
s4, adjusting the driving-in point and the driving-out point according to the adjustment result of the step S3, so that the driving-in point and the driving-out point are both located in the adjusted unaffected area or the adjusted affected transition area, and the vehicle passes according to the adjusted driving-in point and the adjusted driving-out point;
s5, repeating the steps S3-S4 until the vehicle leaves the target road section.
In this embodiment, taking the scenario shown in fig. 2 as an example, according to the severe weather influence degree, the target road section is sequentially divided into an area not affected by severe weather, an area affected by weak severe weather (i.e., an influence transition area), and a severe weather influence area. From the toll station 6, the jurisdiction of a certain highway management company, that is, the target road section area range is started. Wherein, the downstream of the toll station 1 is a bad weather influence area, a bad weather influence weak area is arranged between the toll stations 3 and 1, and a bad weather influence free area is arranged between the toll stations 6 to 3. The traveling direction of the vehicle is a direction from the toll station 6 to the toll station 5.
In this embodiment, in step S2, traffic identification information is set for the passing vehicles, specifically, taking a vehicle on the expressway on the toll station 6 as an example, a driver fills in identity information, license plate information, and drives away from the toll station on the expressway, such as the toll station 1, at the client of the expressway management system, so as to make a trip reservation. That is, the entry point of the vehicle is the toll booth 6, and the exit point is the toll booth 1.
The green code is obtained after the information is filled and checked by the expressway management system; if the toll station filled by the driver is the downstream toll station of toll station 1, a red code will be obtained and the driver will not be able to pass through the highway or will need to refill the destination.
Further, the driver can scan through the toll station 6 by means of the green code to drive into a high speed, and the driver can drive out of the high speed at the toll station 1 or upstream thereof to complete one pass based on the pass code. If the driver leaves the toll station downstream of the toll station 1 through the severe weather influence area, the driver is considered as illegal, the credit of the driver is influenced (both the vehicle and the driver are influenced), the yellow code is automatically generated when the pass code is used for the next time, the system audit is not passed, and the expressway of the section cannot be passed under the severe weather condition during the punishment period. Wherein the punishment times are determined by the manager.
In the embodiment, in step S3 and step S4, along with expansion or contraction of the influence range of bad weather, the travel range is elastically adjusted by pushing the message of the mobile phone client. Taking the above vehicle as an example, if the bad weather affected area is enlarged between the toll stations 2 and 1, the driver is informed to drive away from the toll station 2 by means of a short message or voice. If the driver still leaves the toll station downstream of the toll station 1, he is considered as a violation, affecting his credit. If the bad weather influence area is reduced to a downstream toll station of the toll station 1, informing a driver that the vehicle can continue to travel forward to the downstream toll station for departure in a mobile phone short message or voice mode; if the area of influence is completely lost, the driver will be informed of free travel.
In this embodiment, in order to ensure the traffic safety and improve the traffic efficiency, it is necessary to perform the clearance control on the vehicleSo that the release time interval between the release vehicles is h t And makes the release period of the release vehicle be T.
As shown in FIG. 3, the toll station 3 is the boundary of a road section with weak bad weather, the toll station 6 is the farthest toll station from the bad weather region, the diagonal arrow indicates the space-time track of vehicles, and the safety distance s between vehicles must be kept in the road section with weak bad weather safe Running; wherein the safety distance s safe Determined from specifications or manager experience.
The release time interval h is determined according to the following formula t ：
wherein ,ssafe V for a safe distance between vehicles in regions with weak bad weather influence f The average running speed of the vehicle in the region with weak influence of severe weather.
The release period T is set from the initial entry point of the target road section, and the release periods at other entry points are the same as the initial entry point. Specifically, if the toll booth 6 is the initial entry point of the target link, the release period T is determined for the toll booth 6 according to the following formula:
wherein k is the number of entry points in the unaffected region, deltax i To the ith distance, v, in the unaffected region c For average speed of travel over unaffected zone segments, P 0 Is a set value. Specifically, the k takes a value of 3, that is, the unaffected area includes toll stations 6, 5 and 4, and the total number of the entry points is 3; Δx 5,6 To the 1 st distance in the unaffected region, deltax 4,5 To the 2 nd distance in the unaffected region, deltax 3,4 3 rd spacing in the unaffected region; the P is 0 The value is the number N of vehicles passing through the toll station 6 6 Number of vehicles N 6 The value of (2) is determined by the manager, if the number of queuing vehicles for backlog of the toll station is reduced to a small extent, N is calculated 6 Smaller, otherwise handle N 6 And becomes larger.
In order to meet the traffic demand and further ensure traffic safety of vehicles, the number of vehicles released from the entry point is limited so that the number of vehicles is N. As shown in fig. 3, the toll stations 5, 4, and 3 may each be an entry point, specifically, for the number N of vehicles passing from the toll station 5 5 ：
wherein ,represents a downward rounding, deltax 5,6 Which is the distance between the toll station 5 and the toll station 6.
For the number N of vehicles passing from the toll station 4 4 ：
wherein ,represents a downward rounding, deltax 4,5 Which is the distance between the toll station 4 and the toll station 5.
For the number N of vehicles passing from the toll station 3 3 ：
wherein ,represents a downward rounding, deltax 3,4 Which is the distance between the toll station 3 and the toll station 4.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present invention and not for limiting the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the technical solution of the present invention, which is intended to be covered by the scope of the claims of the present invention.
